Application filed June 5, 1909. .Serial No. 500,269. i

To all whom it may concern:

Be it known that I, JOSEPH H. WOOD, of

Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Cutting Apparatus, of which the following is a full, clear and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal side elevation, partly in section, showing cutting apparatus constructed and arranged in accordance with my invention. Fig. 2 is a top plan of the same. Fig. 3 is an end elevatlon of the apparatus shown in Figs. 1 and 2. Fig. 4 is a detail elevation, partly. in section, showing the gripping mechanism, and showing the cam surfaces as arranged in actuating the gripping and cutting mechanisms. Fig. 5 isa plan, and Fig. 6 a detail elevation showing the gripping and cutting mechanism as secured in the r m of the measuring wheels;

Fig. 7 is a detail sectional end elevation on the line VTL-VH of Fig. 5. Fig.8 is a similar view on the line VIII-VH1 of Fig. 5. Fig. 9 is a detail sectional plan on v the line l[X-IX of Figs. 7 and 8, showing the gripping mechanism and cutting mechanism as arranged during the cutting operation.

. My invention relates to the cutting of long flexible materials, such as rope,into a large number of short pieces. I

The apparatus is primarily designed for cutting pieces from a coil of rope, which are then used in tying pipe into bundles; Heretofore in cutting such ropes it has been the custom to take a coil of rope and to cut it transversely of its length along one side of its axis. This-operation results in each layer of the coil varying in length from the other layers, and as a result some of the ropes are of the desired length, whileothers are either shorter or longer than necessary. This results in a waste which has been the cause of considerable expense in factories usin a large amount of such materials for bundlm The object of the invention .is to provi e apparatus constructed and arranged to mee anically grasp and hold the end of a coil of rope, or like material, to successively measure a piece ofthe desired length, to sever the measured piece from the coil, re-

lease the cut piece, and to grasp and hold thev nected by means of slow tin cut end of the coil during and after each measuring and cutting operation.

Specification of LetterslP'atent. Patented Jan. 25,- 19M).

Another object of my invention is to provide improved mechanism constructed and arranged to sever the material, and to cut the ends of the material square and clean.

A further object of the invention is to provide a clamping mechanism constructed and arranged to mechanically grasp and hold, and to then release the end of the coil of material at predeterminedintervals. A still further object of the invention is to provide cutting apparatus having improved means for yieldingly holding and controlling'the movement of the coil of material while it is being unwound during the cutting operations.

In the drawings, 2 and?) represent measuring wheels which are mounted on and are rotated with the shaft 4. This shaft is conand the belt 6 with the driving motor 7, and is mounted in bearings 4: on the standards or down gearing 5 sides 8 of the apparatus,the standards and motor 7 being mounted on the bed plate 9 of the apparatus. Also mounted on the bed plate 9 in bearings 10 is a shaft 11, which is provided with an adjustable spool or drum 12 on which the coil of rope or other material to be cut, is mounted during the cutoperations. The measuring wheels 2 an 3, as shown, are of different diameters, to enable pieces of different lengths tobe cut from the coil of rope on the drum or spool 12. The apparatus is also provided with a pivoted arm 13, mounted on the post 14, which is secured to the bed plate 9, and on the arm 13 are idler pulleys 15 and 16 which serve to guide the material during its passage from the drum 12 to one or the other of the measuring wheels 2 and 3.

The arm 13, as shown, is mounted in the socket 1 1 on the post 14, in position for guiding thematerial as it is uncoiled in its passage from the reel or spool 12 to the wheel 2. When the wheel 3 is to be used to measure and out the materials,'the arm 13 is placed in the socket 14 provided on the by means of the spring 18, which is connected to the arm 17 in such manner that when the arm is depressed into a horizontal position the spring will tend to hold it in provided, as shown, with three pockets, and

removably mounted in each of the pockets is a gripping device 19 and cutting device 20. The gripping mechanism has opposing clamping faces 2l and 22, the jaw 22 being mounted so as to reciprocate in its seat and being yieldingly held in its open position by means of the helical spring 23. Each of the standards 8, on which the wheels 2 and 3 are rotatably mounted is provided with annular cam surfaces 24 and 24, and adjustably mounted on the sliding member 22 of the gripping device is an anti-friction roller 25 which is arranged to contact with and be moved byone of the cam surfaces 24 on the standards 8. The support 26 for the anti-friction roller 25 is ad ustablysecured to the removable clamping jaw 22, being held in its adjusted position by means of the jam nut 27. The cutting device comprises 0 positely facing knives 28 and 29,-

the kni e 29 being movably secured in its seat. The knife carrier 30 on" which the knife 29 is mounted is adjustably secured to the'support 31 on which an anti-friction roller 32 is secured. The roller 32 engages with one of the annular cam surfaces 24 which are provided on the standards 8 of the apparatus. The knives 29 are yieldingly held out of their cutting position by means of the helical 3 rings 33. The knives 29 are removably hel in place on their supports, being provided with transversely extending openings or holes, through which the dowel pins 34 extend, and the movement of the knives 29 and the clamping jaws 22 is limited by means of adjusting nuts 36.

as to have a circumferential roove, similar to that formed in a rope pulley, in which the rope rests during the measuring and cutting operations. Three separate gripping and cutting mechanisms are shown on each wheel, although the number may be varied, or, the diameter of the wheels may be changed in order to cut pieces of greater or lesser lengths from a coil of the material being operated upon.

In the operation of my improved apparatus, a coil of rope or like flexible material is mounted on the spool 12, and one end is passed around the idler pulleys 15 and 16, and is secured between the clamping jaws of one of the clamping devices 19 on one'of the other ofthe wheels 2 or 3. The motor is then caused torotate which will in turn cause the wheels 2 and 3 to rotate. As the wheels are rotated in the direction of The measuring wheels 2 and 3 are constructed so the arrow .on Fig. 1, the rope will be unwound from the spool 12, and when the wheels have rotated far enough to bring the next cutting mechanism into contactwith the rope the cam surfaces 24 and 25 will cause the gripping mechanism to grip the rope behind the cutting mechanism, when the cutting knife will be actuated to sever a piece of the rope from the coil, which is then held by clamping devices at two points on the wheel. The cam surfaces are arranged to cause the gri ping mechanism to retain its hold on the en of the coil of rope, after each cutting operation, until such time as the next cutting device on the periphery of the wheel is actuated by the cam surface to sever the rope.

As shown in the drawings, but one drum 12 is provided for the two measuring wheels 2 and 3, although two drums may be employed, in which case the wheels 2 and 3 can be operated simultaneously to cut the materials into pieces of different lengths, and while two measuring wheels are shown,

obviously but one of such wheels may be used when desired.

The advantages of my invention will be apparent to those skilled in the art.

By the use of my improved apparatus, a coil of ro e or similar flexible material is mechanica ly operated upon to successively 0 cut it into a larger number of small pieces which are of the same length. There is no waste of the materials, and the operation is entirely automatic after the end of the coil rope has been placed in position in the first of the gripping mechanisms.

Modifications in the construction and arrangement of the parts may be made without departing from my invention.

I consider myself the first to construct apparatus which is adapted to mechanically cut a coil of rope or like materials into a large number of pieces of definite length, and to perform these operations successively upon different portions of a coil of rope without the attentlon of the operator, and I intend to claim such construction broadly.
